Quality Control

Our polyester polyol resin is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Key parameters including hydroxyl value, acid value, viscosity, and color are rigorously tested. A Certificate of Analysis (COA) documenting these specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive). Keep container tightly sealed when not in use to prevent moisture absorption, which can affect product performance.
